2.2.GROVE INTERFACE

4p ibala elilahliweyo le-2.0mm I-CORINK I-GROVE interfaces, i-wiring yangaphakathi kunye ne-GND, i-5V, i-GPIO4, i-GPIO13 ixhunyiwe.

INKCAZELO YOMSEBENZI

Esi sahluko sichaza i-ESP32-PICO-D4 iimodyuli ezahlukeneyo kunye nemisebenzi.

3.1.CPU NENKUMBULO

I-ESP32-PICO-D4 iqulethe i-Xtensa® yamandla aphantsi amabini angama-32-bit LX6 MCU. Imemori ekwi-chip equka:

I-448-KB ye-ROM, kwaye inkqubo iqala kwi-kernel function calls
Ngomyalelo we-520 KB kunye ne-SRAM yokugcina idatha (kubandakanya imemori ekhanyayo 8 KB RTC)

imowudi, kunye nokugcina idatha efikelelwe yi-CPU engundoqo
Imemori ecothayo ye-RTC, ye-8 KB SRAM, inokufikelelwa yicoprocessor kwimowudi yokulala

Ye-1 kbit ye-eFuse, eyi-256 bit system-specific (idilesi ye-MAC kunye neseti yetshiphu); i-bit eseleyo ye-768 igcinelwe inkqubo yomsebenzisi, ezi nkqubo zeFlash ziquka ufihlo kunye ne-ID ye-chip

3.2.INGCACISO YOKUGCINA

3.2.1.I-Flash yangaphandle kunye ne-SRAM

I-ESP32 ixhasa i-flash yangaphandle ye-QSPI emininzi kunye nememori yokufikelela okungahleliweyo (i-SRAM), ene-hardware-based AES encryption ukukhusela iinkqubo zomsebenzisi kunye nedatha.

I-ESP32 ifikelela kwi-QSPI Flash yangaphandle kunye ne-SRAM ngokugcina indawo yokugcina. Ukuya kuthi ga kwi-16 MB isithuba sekhowudi yeFlash yangaphandle ifakwe kwi-CPU, ixhasa i-8-bit, i-16-bit kunye ne-32 bit ukufikelela, kwaye inokuphumeza ikhowudi.

Ukuya kuthi ga kwi-8 MB iFlash yangaphandle kunye ne-SRAM eboniswe kwindawo yedatha ye-CPU, inkxaso ye-8-bit, i-16-bit kunye ne-32-bit yokufikelela. I-Flash ixhasa kuphela imisebenzi yokufunda, i-SRAM ixhasa ukufunda nokubhala imisebenzi.

I-ESP32-PICO-D4 4 MB ye-SPI Flash edibeneyo, ikhowudi inokuthi ifakwe kwi-CPU indawo, inkxaso ye-8-bit, i-16-bit kunye ne-32-bit ukufikelela, kwaye ingenza ikhowudi. I-Pin GPIO6 ESP32 ye, GPIO7, GPIO8, GPIO9, GPIO10 kunye ne-GPIO11 yokudibanisa imodyuli edibeneyo ye-SPI Flash, engacetyiswa kweminye imisebenzi.

3.3.IKHRISTU

I-ESP32-PICO-D4 idibanisa i-crystal oscillator ye-40 MHz.

3.4. ULAWULO lwe-RTC NOKUSETYENZISWA KWAMANDLA ANGAPHANTSI

I-ESP32 isebenzisa ubuchule obuphambili bolawulo lwamandla inokutshintshwa phakathi kweendlela ezahlukeneyo zogcino lwamandla. (Jonga kwiThebhile 5).

Imowudi yokugcina amandla
-Imo esebenzayo: I-RF chip iyasebenza. I-chip inokufumana kwaye igqithise isignali yesandi.
Imowudi yokulala yeModem: I-CPU inokubaleka, iwotshi inokumiswa. Wi-Fi / Bluetooth baseband kunye RF
Imowudi yokulala ukukhanya: i-CPU inqunyanyisiwe. I-RTC kunye nememori kunye neeperipherals ULP coprocessor operation. Nasiphi na isiganeko sokuvuka (i-MAC, inginginya, isibali-xesha se-RTC okanye isiphazamiso sangaphandle) siya kuvusa itshiphu.
-Imowudi yobuthongo obunzulu: yinkumbulo ye-RTC kuphela kunye neeperipherals kwimeko yokusebenza. I-WiFi kunye ne-Bluetooth yoqhagamshelwano lwedatha egcinwe kwi-RTC. ULP coprocessor inokusebenza.
- Imowudi ye-Hibernation: I-oscillator ye-8 MHz kunye ne-coprocessor ULP eyakhelweyo ivaliwe. Imemori ye-RTC yokubuyisela unikezelo lwamandla icinyiwe. Sinye kuphela isibali-xesha se-RTC esikwiwotshi ecothayo kunye ne-RTC GPIO emsebenzini. Iwotshi ye-RTC ye-RTC okanye isibali-xesha sinokuvuka kwimowudi yokuHibernation yeGPIO.
Imowudi yobuthongo obunzulu
Imowudi yokulala ehambelanayo: imowudi yokugcina amandla itshintsha phakathi kwe-Active, iModem-ubuthongo, imowudi yokulala ukukhanya. I-CPU, i-Wi-Fi, iBluetooth, kunye nexesha lokuseta kanomathotholo ukuze kuvuswe, ukuqinisekisa uqhagamshelo lwe-Wi-Fi / Bluetooth.
-Iindlela zokujonga i-sensor ye-Ultra Low-power: eyona nkqubo iphambili yimowudi ye-Deep-sleep, i-ULP coprocessor ivulwa ngamaxesha athile okanye ivalwe ukulinganisa idatha ye-sensor.
I-sensor yokulinganisa idatha, i-ULP coprocessor yenza isigqibo sokuba ivuse inkqubo engundoqo.
